Be it known that I, BENJAMIN WIROTH, a citizen of the United States,residin at tate of Pennsylvania, have invented certain new and useful 1Improvements in Vehicleof the invention, such as will enable othersskilled inithe art to which it appertains to This invention is anlmprovement in 7 a resilient hub therefor. t

An object of the invention is to provide an improved vehicle wheel inwhich'the hub portion thereof is so constructed as to cushion the wheelagainst vibrations and other shocks incident to the travel of the wheelAnother object 1s-to provide novel means for transmitting the power fromthe; axle to thewheel in such manner that the same will be driven whenthe axle is rotated ineither direction.

i absorbing members of improved construction which will yieldablyiresistthe strain and distribute the. same when traveling over rough surfaces.

The ring 30 is recessed to accommodate the rollers 29, as shown in Figs.1 and 7 and. lies snugly between the ring plate 12 and the disk 31. Therollers29 lie in radial slots 3'7'formed in the disk 31 and this disk 31is carriedrby a boxing 33' upon which the I sleeves 18 are directlydisposed,'the boxing matter. The ends 16 and 4:3 respectively of r 38being fastened to the axle 10 by means of a pin 36 passed throughalining perforations in the boxing and axle. The disk 31,

as illustrated, lies between the inner ends of the sleeves 18. Upon theinner end portion of the axle is disposed an annular plate '50. whichsnugly. fits the axle and is ofsufficient diameterto cover the centralopening 17 of the casing 15 and thus exclude foreign the casings 15 and42 are removable.

' From the above description it will be understood that the axle mayhave a limited movement radially within the casings and against thetendencies of corresponding sprlngs 20 which w1ll serve to absorb shocksand there will thus be provided a cushion- .ing effect, the rollers 24'bearing at all times against the ing casings.
